Question

An organelle found in a liver cell would best be identified as a lysosome if its primary function was which of the following?

A) Processing and packaging of cellular materials prior to export
B) Harvesting of light energy to produce carbohydrates
C) Detoxification of poisonous molecules within the cell
D) Digestion of macromolecules and old organelles

Answer 1

A liver cell organelle functioning primarily for the digestion of macromolecules and old organelles would be identified as a lysosome, which contains enzymes to break down and digest these substances.

Step-by-step explanation:

An organelle found in a liver cell would best be identified as a lysosome if its primary function was the digestion of macromolecules and old organelles. Lysosomes are membrane-bound organelles containing hydrolytic enzymes necessary for breaking down various biological polymers such as proteins, polysaccharides, lipids, nucleic acids, and damaged organelles. These organelles play a crucial role in cellular waste disposal, autophagy, and the destruction of pathogens via phagocytosis or endocytosis.
